Application October 25, 1950, Serial No. 192,057

This invention relates to liquid mixing apparatus and particularly toapparatus for intermixing predetermined volumes of two or more liquids.

Soft drink concentrated syrups are prepared with sumcient sugar contentto prevent fermentation thereof. However, when thi syrup is dilutedbefore carbonating the drink, it will spoil in a relatively short time.Therefore, it is necessary to mix only small portions of the liquid tobe carbonated to prevent wastage from spoiling of the dilutedconcentrate.

It is an object of my invention to provide apparatus constructed to mixpredetermined volumes of two or more liquids by an automaticallycontrolled mechanism.

It is another object to provide mechanism for mixing a batch of liquidproduced by intermixing predetermined volumes of two or more liquidsthrough a single cycle of operation.

More specifically, it is an object to provide two or more liquid supplytanks, each having a liquid delivering bucket, normally positionedtherein and adapted to be shifted from filling position to dumpingposition to discharge liquid from the bucket into a single mixingcompartment.

It is still another object to provide a number of liquid carryingbuckets in the form of elongated troughs, each being closed at one end,and mounted on a single shaft to be swung upwardly from filling positionto dumping position and thereafter returned to filling position, asingle revolution power source being provided for actuation of a pitmanto oscillate said bucket on the shaft and operate the mechanism througha single cycle of operation.

These and other objects and advantages will more fully appear from thefollowing description made in connection with the accompanying drawingswherein like reference characters refer to the same or similar partsthroughout the several views and in which:

Fig. 1 is a side elevational view of my mixing apparatus with a portionof the wall broken away and showing the mixing buckets in fillingposition by full lines and in dumping position by dotted lines.

Fig. 2 is a top plan view of the structure shown in Fig. 1.

Fig. 3 is a transverse vertical sectional view taken substantially alongthe line 33 of Fig. 2.

Fig. 4 is an elevational view showing the single revolution motor andthe pitman actuated therey;

Fig. 5 is a diagrammatic view of the electric 2 Claims. (Cl. 222-56) 2wiring circuit for the apparatus illustrated; and

Fig. 6 is a fragmentary traverse sectional view taken substantiallyalong the line 8-6 of Fig. 4.

As shown in the accompanying drawings, I provide a compartmented liquidconfining tank 8 having, in the form shown, a pair of supplycompartments 9 and I8 divided by a longitudinally disposed partition IIterminating at a transversely disposed partition I2, which forms amixing compartment I3. A transversely disposed pivot shaft I4 is mountedacross the upper portion of the tank 8 and in the form shown, isdisposed directly above the transverse partition I2. A pair of liquidcarrying and delivering buckets I5 and I6 are journalled'for oscillationin side by side relationship on said shaft I4. These buckets I5 and. I6are in the form shown, elongated troughs, which are closed at the freeends thereof, a partition I5a closing the end of the water supply troughI5 and. a partition I6a having the adjustable level controlling notchI611 closing the end of syrup supply trough I6. The two troughs I5 andI6 are rigidly interconnected by an inverted U-shaped yoke I1, and areslightly spacedto straddle the longitudinal partition II, the bucket I5operating in water supply compartment or tank 9, and the bucket I6operating in syrup supply compartment I0.

A source of actuating power, such as the single revolution electricmotor I8 is provided, and in the form shown, is mounted ona suitableplatform I9 fixed at one end of the tank 8. The

motor I8 is wired in a conventional manner, so that whenever the switch29 has been closed to start, the motor, the same will continue tooperate for a single revolution, and then will be automatically stopped.The details of this internal wiring of the motor I8 are not shown, butthere are a number of such motors conventionally being produced for salesuch as a model 604B6 motor made by Minneapolis Honeywell Company,Minneapolis, Minnesota, and shown generally in Patent No. 2,194,701. Itshould be noted that the motor disclosed in said patent must be modifiedto produce a 360 rotation instead of the 180 rotation produced by thecircuit and limit switches illustrated in said patent. The rotary shaftof motor I8 is disposed transversely of the tank 8, and a crank arm 20is fixed thereto. The crank arm 20 has an elongated slot 20a. formed inthe outer portion thereof, as best shown in Fig. 4. An adjustment pin 22is inserted through said slot 28a, as best shown in Fig. 6. A bushingand collar unit 2| is journalled on said bushing to be reciprocated bycrank arm 20
